We are developing the fastest laser Microtexturing system of the world, but how does it work? It is based on a method called 𝗗𝗶𝗿𝗲𝗰𝘁 𝗟𝗮𝘀𝗲𝗿 𝗜𝗻𝘁𝗲𝗿𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗣𝗮𝘁𝘁𝗲𝗿𝗻𝗶𝗻𝗴, or short 𝗗𝗟𝗜𝗣, in which two laser beams are superimposed and create an interference pattern. This pattern illuminates the substrate and, when the laser intensity is high enough, this can be treated directly, creating surface features in the range of a few micrometers.
PROMETHEUS' system uses a millimeters-large laser beam in order to process the substrate faster, still keeping the features size small enough for producing surface functions like self-cleaning, decoration and friction reduction or increase.
Fraunhofer IWS is in charge of developing and constructing the main functional component of the PROMETHEUS system, which is a compact module for DLIP.
The module has been assembled and is currently under testing.
